damper manufacturer introduces the characteristics of pulse damper and building damper

damper manufacturer: why is there pulse when pulse damper is installed?

Since the metering pump is a reciprocating positive displacement pump, pipeline pulses will be generated during work. In order to eliminate pipeline pulses, pulse dampers must be installed. Recently, there has been a problem. Even if pulse dampers are installed on fixed displacement pumps, pipeline pulses will be generated. Share this case together.

Damper Manufacturer: Air Pulse Damper

Analyze pulse dampers, also known as pulsation dampers and pulse dampers, which are containers used to eliminate pulsation. The main types are diaphragm type, airbag type and air box type, of which airbag type is effective.

When purchasing the shock absorber shell, the company's customers first make a rough judgment according to the material and operating pressure. When the general operating pressure exceeds 5Mpa and the volume of the shock absorber shell exceeds 0.6L, the customer is requested to choose the high-pressure airbag type or the high-pressure air type, and the air tank type pulse damper is activated during the installation process. At the beginning of operation, the removal effect of the pipeline pulse is very good, but after a while the pipeline pulse occurs obviously. Why?

So, why is there a pipeline pulse after opening the tank?

The gas in the air damper gradually dissolves under the pressure of the medium, and the compressible gas becomes less and less, and the buffering effect becomes worse. The first two pulse dampers are filled with air before working, that is to say, in action Still in the shell of the shock absorber, there is air in the gas tank type at the beginning, and after a while, there is no air in it. This is the cause of the pipeline pulse. How can it be solved? There is a pressure gauge at the upper end of the air box type shock absorber shell. Remove the pressure gauge and put in a little air to get the action effect again.

Damper Manufacturer: Principle and Advantages of Building Damper

1. Principle

The traditional seismic method is to dissipate seismic energy through plastic deformation of the structure itself. Its essence is to use the structure itself and its components as "energy consuming" elements, which will inevitably cause different degrees of damage to the structure, even serious damage and collapse. Structural control is to set up control devices on the structure, the control mechanism and the structure together prevent dynamic effects such as earthquakes and reduce the dynamic response of the structure.

2. benefits

The damping method of the additional energy-absorbing and damping device on the structure takes the friction damper passively controlled by the structure as one of the energy-consuming devices, which has strong energy-consuming capacity, little effect of load size and frequency on performance, simple structure, convenient material acquisition, low cost and good application prospect, especially has unique advantages in controlling the near-fault seismic response of the structure and the seismic response of the middle and high-rise structure, the mechanism of the vibration control of the structure by the friction damper is that the damper slips or deforms under the specified load before the yield of the main structural components, dissipates the seismic energy through friction or attenuation, and at the same time, the self-excited oscillation period of the structure after deformation becomes longer, so as to realize the reduction of the seismic response of the structure.
